Application ied February 11, 1908. Serial No. 415,291.

To all whom it 'may clio/Leere.'

Be it known that l, LnwnN R. NnLsoN, a citizen of the United States, residing at Peoria, in the county of Peoria and State of illinois, have invented certain new and useful improvements in Nozzles; and l do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to malte and use the saine.

My invention relates to certain new and useful improvements in nozzles, whereby a nozzle stem is provided which is simple in construction, durable and cheap in. lirst cest.

More particularly, my .invention has reference te a hose nozzle capable of ready adjustment to adapt it to throw a spray or a solid stream and is very easily manipulated for that purpose.

My invention relates also to means for accomplishing a ready attachment and detachment of the nozzle stem from the sleeve forming a part of the nozzle, without the use of threaded connections.

That my invention may be more fully understood, reference is had to the accompanying drawings, in which- Figure 1 is a side elevation showing my invention connected with a hose pipe. ll1 2 is a sectional view showing in elevation a portion of my improved nozzle and detailed parts thereof. Fig. 3 is also a sectional view through the nozzle showing details of construction. Fig. 4 is a plan view of the coupling sleeve. Fig'. 5 is a sectional view of the same. Fig. 6 is a detailed view showing a plan of a threaded collar provided with radially disposed lugs. Fig. 7 is a detailed view of a reach or stop. Fig. S is a stop plate. Fig. 9 is a sectional view showing a 'modified forni of embodiment of my invention. Fig. 10 is alse'a sectional view of my invention showing a modified form of embodiment of the same.

in the drawings, 1 is a nozzle stem in form substantially as l prefer to construct the saine, it being provided with a vllared eiltwa'rd end, and having the opening as shown, the interior bore thereof being made in two diameters as shown. The lower portion is provided with a tapered shoulder 3 adapting it for engagement with the tapered depression in the sleeve Li. 5 is the valve suitably formed at its upper end to be projected within the opening 2 in the forward end of the nozzle stern, a short distance, but

the main body of the same being ot larger dimensions than that of the opening. '.lhe valve is threaded as shown and is adapted to be carried within the threaded sleeve having the radially disposed lugs 7 .lhis sleeve is adapted to be supported as shown with the lugs engaging the wall of the nozzle stem and to remain in iixed position. The valve is slotted as at S and is adapted to be engaged by the reach or stop t) which extends downwardly and is lu'oiulened at its base as at 10 as best shown in Figs. 2 and 7, and is provided with laterally extending shoulders l1, having circular forni, adapted to iit within the lower portion of the nozzle stem and within such shoulders are provided the circularly formed grooves l2, the lower portion of the interior bore olI the nozzle stein being also provided with circular groove at at 13 adapted to match withv the grooves in the shoulders of reach. il.

lx-l is an open ring preferably formed of round brass wire andA is best shown in Fig. I

and is of such size that when compressed within the grooves 12 which are of sullicient depth to completely embrace the wire ring, it may be inserted. within the lower end of the nozzle stem but will spi'ing outwardly when in uxtapositien lo engagev the said groove lil in the nozzle stem, the depth of the groove 13 being such that when the ring is seated therein, the interior edge thereof will project beyond the interior face of the bore sulliciently to support the reach or stop t) in such a manner that it may be readily turned thereen, thereby providing a simple and a very ellicient support for the reach or stop and also providing a means of assembling of the very simplest cha rae ter.

.l5 is a rubber washer formed with interiorly extending lips thinner than the main body of the washer which are adapted to bear over the joint formed between the matching shoulders on the nozzle stem and the sleeve. The interior wall of the opening in thc sleeve l is recessed as best shown Vin Figs. 3 and 5 to form a seat for the washer 15. le is a stop plate adapted to be supported in contact willi the lower edge of washer 15 and is provided with the stop projections i7 (best shown in liig. 8), this stop plate 1.6 being adapted to engage the lower end of the Vlinger l) in the manner best shown in Fig. d.

1S is a rubber washer adapted to bear against the stop plate 16 to hold the same in place.

rl`he lower portion ot the interior ol' sleeve 4l is threaded as shown to facilitate engagewith with the ordinary hose connection.

To facilitate the connection of the nozzle stein l with. the sleeve Ll, the lugs i9 are provided upon the upper edge of sleeve d, the saine being inturned and suitably formed to engage the upper lace of the shoulders 2:3 upon the nozzle stein.

2G is a dog having a pivotal connection with stud o i the sleeve and is suitably held under coil spring tension to cause the saine to bear toward the sl eve and is provided with a hooked upper end ad .uted to with the upper face el the shoulder 3 of the nozzle stein. The connection between the nozzle stein and the sleeve is accomplished hooking the shoulder 3 of the nozzle stein under t ie lugs 19 oil the sie-eve, then seating the base of the nozzle stein within the tapered circular opening in the top of the sleeve, then causing the dog 2O to engage with the shoulder 3 upon the nozzle stein. lt will observed that the connection between the nozzle stein and the sleeve is such that the nozzle stein may be readdv turned with the application of a very sinall arnount force and it will also be observed that the connection between the ringer il and the valve 5 is such that as the nozzle stein is turned, the valve will be projected forwardly within the nozzle stein or retracted readily, by ineans of the threaded connection between the valve and collar o, according to l the direction of inoveinent or the nozzle stein, and that the valve will be held against circular :fnoveinent by the stop or reach 9 bearing within the slot therein, and that the stop or reach 9 will be held against movement through the engagement et the lower part thereof' with the stops lkl upon the stop plate l5.

Referring to 3 and l ol the drawings, the particular construction oi the dog 2l) niay be seen in which it will be observed that the tension spring is coiled about the pintle eon nection between the studs of the. dog and the sleeve, while the loop bears underneath the rear end ol the dog, with the free ends thereof extending downwardly and bearing against the outer lace oi' the sleeve, thereby providing a very coinpact ineans for effecting the desired tension on the dog. The ears 2l are provided at the upper end of the dog adapted for engagement to release the dog lroin its engagement with the shoulder 3, likewise the dog ina-y be provided with a tail portion sh own in Fig. 5 upon which pressure niay be applied to accomplish vthe release. lhe use of the washer l5 provided with the thin lips at its inner edge and. not being under the pressure that is sustained by the thicker shoulder portion, will provide such a bearing against the lower end of the stein l as would perniit it to turn readily, also the pressure of the water into the nozzle would cause the thin edges of the Washer to be pressed up again` t the joint between the sleeve and the stein in such a inanner as to inake a perfect closure against leakage.

ln Fig. 9 ol' the drawing, l have shown a inodiiied forni of connection between the nozzle steni and the coupling sleeve. ln this Yligure, d represents the nozzle stein, b the coupling sleeve, the lower eXtreinity ol the nozzle stein being lornied with the shoulder c and the opening in the upper' portion ol the interior ol' the sleeve is inade to eon'l'orin .vith the outer circuinlerence ol the nozzle stein and is suitably recessed to receive the shoulder l'orin a close joint. d is washer oll the saine forni as that previously described as being used n connection vith iny invention provid d with inwardly projecting thin lips adapted to bear over the joint between the shoulder ol the nozzle stein and the sleeve. e is a stop plate in lorniing the saine, as shown in Fig. 5 el' the drav-fings, and

`ry rubber washer. ln this con.- struction, the nozzle stein is suitably Vl`=1i rined to adapt it to be inserted through tlV le sleeve and consequently is el somewhat ditlerent l'orni at its upper end than shown in the other figures. The valve and its nianner ol' support within the nozzle stein and the stop or reach 9 with its ineens ol' support and manner el connection with the nozzle stein the saine as described and shown in connection with the other iigures ol the drawing.

in Png l0, there is also shown a slight modification ol' iny invention. ln this iigure, the nozzle stern and sleeve are connected in the saine inanner in Fig. C', but in this ligure g is a plain. rubber washer adapted to bear over the joint between the nozzle steni connection with the sleeve. b is a stop plate in forni the saine as shown in llig. 8 except that there is provided the upwardly projecting shoulder i which bears against the outer portions ol' the washer g, thus allowing the l'orce ol the water to be applied to the inner edge of the rubber washer' to cause it to be 'lorced up close against the joint between the nozzle stein and the sleeve. Either el' these rnodiiied l'orrns Inay be used with goed resul-ts.

in carrying out iny invention, the sleeve inay be i'orrned with exterior corrugations, or may be otherwise lorined on the portion thereolI adapted to receive the hose pipe instead el providing the saine with threads, and in such event, the washer would have to be inserted through the top part oi the sleeve at the portion where the nozzle steni is adapted to be att-ached and in such use lugs niay be cast within the sleeve below the washer or vpaoking seat to lorin a stop lor the reach 9, and in such use and forni it will be desirable to forni the sleeve in two parts provided with threads at the point indicated by the arrow in l0 whereby the parts may be sepallO rated so that the parts necessary to be contained within the sleeve inay be readily inserted.
